Be it known that I, `Rennen Grissomof Shelby, inthe county oi' Richlauda'nd Stateoi Ohioyhave f invented anew and valuable'ImprovementiujFan- `ningeMills; and I do herebydeclare that the following is a full, clear, and exact description of -the construe- 1 `tion and operationf'of the same, reference, being had to the'annexed drawing making apart of thisspeci-` i cation and to the letters and 'gures of reference markedthereon.` l l I ,l i 1 Figure l, ofthe drawinggisfa perspective viewof my tanning-mill. l l

Figure 2.s a cross-section ofthe same.

,t Figures 3 andv 4 are details]` construction and arrangement of the parts of anfannin'g-lnill, which will be more fully described `in the annexedspeeiiication. t *In the drawing- Ads the frameorcasing of the machine, aty the vided with a valve, b, for regulating the iiow of the grain upon the sieves G, under which'is arranged the board c, by which the grainis conveyed to the hopper 1). The straw, `pieces ofwood, &carecarried over the .sieve G'toithe outside ofthe'case, while the grain falls through the meshesfor lholes of the sieve and is "carried to the hopper il); falling in a thin stream through thcopeuiugD thereof, and is` there exposed tothe. blast of the fan E. The grain is here separated `from thechaiii and dust, which are blown out through sieves F, by whichV theI small seed 'and' timothy are separated #from` lthe goody.. grain, which passes out .through the, opening j in tlie'side of the casing.

The `upper sieve is agitated` by the eccentric shaft gajournaledin the sides of the frame, and having aty Ihe nature ofmyinvention cousistsxin an "improved` upperpart `of which is arranged the hopper B, prothe opening c, while thegrain falls upon lthe lower cv -r 5 I '+I ,i

- .The schedule referred to in these Letters Patent and making paru of the same.

tached to it a spring, h, which gives the sieve a short tittering motion, by lwhich the grain is separated from the straw, coarse chaff, 85e.

A rod, G,'is pivoted to the side of the case, as

4shown at fi. While its lower end is stepped in the sieve F, the upper endv is provided with a spring, la, and' connects to the block l and sieve O, giving a vibratory motion. t Y

A small drawer, H, is arranged under the sieve F to receive the timothy and grass-seeds, and a door, l, is -provided so as to get at the lower sicves, 815e., of the machine. Y The fan-case is provided with sliding shutters m m', .which 'slide upon a rod, n, to regulate the admission ,of air. p s l Having thus described my invention,

' Y`What I claim, and desire to secure by Letters Patent, is- A l. The sieve C and board o, in combination with tue hopper D, opening d, outlet e, and fan E, when said partsare constructed aud-arranged substantially as shown and for the'purpose speeied.

2. The/arrangement of the sieve C and board c, hopper D, opening d, fan E, sieve F, and drawer H, all substantially as shown, for `the purpose set forth.

` 3. The'combination ofthe hopper B, valve b, sieve C, board 4c with the htpper D, opening d, outlet e, fan E, sieve F, drawer H, and opening j, when all the purpose set forth. i ,In testimony that I claim vthe above I have hereunto subscribed my naine Vin the presence of two witnesses.
